High-End Tube preamp with ECC88

[Gost22]

I think it's time you stopped posting designs that are not yours to post, especially since you do not give credit to the original designer or publisher. It is very obvious to me where that one came from.

Tell me Mr.12E1 what's original?
thank you!

Can you specify a Hi-End preamp ?

Just list the features.

One where you didn't cut and paste someone else's COPYRIGHTED image. This is dishonest.

If you copied it, it isn't original. Difficult concept?

Hi SY!
I did not copy it!
You copy it that is making this tube pre-amp with 12AX7 (ECC83-Philips mini WATT) and you will hear the true valve sound, which is called transcendental
Enjoy the real tube sound!

Tube pre amp.

 

[Gost22]

Tube pre amp.

Yes, tube or valve pre-amplifier!!
Firstly it gives the true tube sound, not the of transistor sound cold without a soul ...
That its characteristic design-nice for the eyes!!
Orchestra to convey to you as a concert etc. ...
Cheers!

Yes, you did. That is not a drawing you created.

Yes, he took part in creating!
Here is a picture of the tube pre-amps (Figure 1).

Do you think that using any sort of negative feedback in tube preamp will make the tube sound disappear ?

Negative feedback is minimized (catode resistor R11)-view schematic tube preamp with 12AX7
thank you!

 

[artosalo]

I know this schematic.
But you did not answer my question; does the tube sound disappear if negative feedback is used?

Will not disappear, but a lot is lost.
Try it and you'll see what's the matter

I have tried many times but never noticed that.
On the contrary, NFB has allways improved the "sound".

I know this schematic.

I've seen it before as well- can you recall the source (I can't offhand)?

 

[Gost22]

Come on guys define what is High End tube/valve pre-amp and move on to the topic,...
thanks!

 

[revintage]

22,
You define it instead! All suggestions you have shown are far from what commonly is called "High End". So maybe you seek for "High Coloration"?

 

[tinitus]

all here is high end DIY

Elektor magazine or one of their books / CDs I think.
